Data such as the one linked below is available and i was wondering if it would be a good idea to upload it after permission is received and whatnot.
thanks.
Building Footprints – Greater Shepparton | Datasets | data.gov.au - beta
It would, but by my understanding, data.gov.au is just consolidating info from lots of other sites, so we would, in this case, need permission & a waiver from Shepparton City Council, not the data site.
However, please feel free to contact SCC for permission! 
Just to add to @Fizzie41 reply, also have a read of Import/Getting permission - OpenStreetMap Wiki
This particular dataset only contains a small portion of all buildings within the LGA, likely only those owned and/or maintained by the council. Some are already mapped. So overall I don’t think it’s worth the effort here.
In general I’m supportive of importing building footprints where
- we have acceptable licensing,
- the local community is on board
- there is an appropriate process to,
a) prepare the data
b) quality check the data
c) ensure it is of sufficient quality
d) duplicate data is not added
